Cust having bother with newly installed Mira Mode rear fed shower that is constantly dripping. Not seen it yet going tomorrow but want to be pre-armed before I go. Any help welcome. Thanks.
Sounds like the Flow Sensor,( To check the wires at the pcb(J7) should be reading- Pink 5 volts dc - White 18 volts dc - Grey 0 with the tap running)
If all else fails phone the tech line (number on the back of the boiler manual)
